Notes:

For the Present_Value property it is permissible to set a Map Descriptor length >1. This will cause a read of the Present_Value property of consecutive BACnet
objects of the type defined by this Map Descriptor

The number of properties that can be read or written at once is limited by the maximum APDU message length.

Message segmentation is not supported.
These map descriptors form part of the read transaction defined by
